This page provides an overview of Funtoo Linux sub-architectures (also called ''subarches'') designed for quick and easy reference. Funtoo Linux provides optimized installation images for all sub-architectures listed below. Clicking on a particular subarch will bring you to a detail page where you can learn more about that subarch and download a stage3 for installation.
=== Installing the Stage 3 tarball ===
+
  
After creating filesystems, the next step is downloading the initial Stage 3 tarball. The Stage 3 is a pre-compiled system used as a starting point to install Funtoo Linux. Load one of the following URLs in another browser window:

=== How to Identify your CPU ===
  
Inside <code>/funtoo-current/x86-64bit/</code> on one of our mirrors, you'll see a bunch of directories for various ''subarches'' of Funtoo Linux. Subarches are builds of Funtoo Linux that are designed to run on a particular type of CPU, to offer the best possible performance. They also take advantage of the instruction sets available for each CPU.
+
There are a couple of ways to identify the type of CPU you have. One option is to use the {{c|lscpu}} command:
 +
{{console|body=
 +
# ##i##lscpu
 +
}}
  
If you are using an AMD-based CPU, download a stage3 from <code>generic_64</code>, <code>amd64-k8</code>, <code>amd64-k10</code>, <code>amd64-bulldozer</code>, <code>amd64-piledriver</code> or <code>amd64-steamroller</code>.  See [[Subarches]] for help figuring out what AMD subarch is best for you.
+
If the {{c|lscpu}} command is unavailable, you can get similar information via {{f|/proc}}:
 
+
{{console|body=
If you are using an Intel-based CPU, download a stage3 from <code>generic_64</code>, <code>atom_64</code>, <code>core2_64</code> or <code>corei7</code>. Note that <code>corei7</code> is ideal for any modern Intel processor, including Core i3 and Core i5, and many Xeons.
+
# ##i##cat /proc/cpuinfo {{!}} grep "^model name" {{!}} uniq
 
+
model name : Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz
If you are using a 32-bit CPU, download a stage3 from <code>generic_32</code>, <code>i686</code>, <code>core2_32</code>, <code>atom_32</code> or <code>athlon-xp</code>.
+
}}
 
+
==== Setting the Date ====
+
 
+
{{fancyimportant|If your system's date and time are too far off (typically by months or years,) then it may prevent Portage from properly downloading source tarballs. This is because some of our sources are downloaded via HTTPS, which use SSL certificates and are marked with an activation and expiration date. However, if you system time is relatively close to correct, you can probably skip this step for now.}}
+
 
+
Now is a good time to verify the date and time are correctly set to UTC. Use the <code>date</code> command to verify the date and time:
+
  
 +
The {{c|cpuid}} command is another option and can provide other interesting information:
 
<console>
 
<console>
# ##i##date
+
###i## emerge cpuid; cpuid | tail -n 1
Fri Jul 15 19:47:18 UTC 2011
+
 
</console>
 
</console>
  
If the date and/or time need to be corrected, do so using <code>date MMDDhhmmYYYY</code>, keeping in mind <code>hhmm</code> are in 24-hour format. The example below changes the date and time to "July 16th, 2011 @ 8:00PM" UTC:
+
{{note|Search is your friend.
 
+
Take the chip name gathered, then google wiki chipname to find the wikipedia article for your chip. The right hand column of your processors wiki article will list the microarchitecture.
<console>
+
# ##i##date 071620002011
+
Fri Jul 16 20:00:00 UTC 2011
+
</console>
+
 
+
==== Download the Stage3 ====
+
Once you are in your Funtoo Linux root filesystem, use <code>wget</code> to download the Stage 3 tarball you have chosen to use as the basis for your new Funtoo Linux system. It should be saved to the <code>/mnt/funtoo</code> directory as follows:
+
 
+
<console># ##i##cd /mnt/funtoo
+
# ##i##wget http://ftp.osuosl.org/pub/funtoo/funtoo-current/x86-64bit/generic_64/stage3-latest.tar.xz
+
</console>
+
 
+
Note that 64-bit systems can run 32-bit or 64-bit stages, but 32-bit systems can only run 32-bit stages. Make sure that you select a Stage 3 build that is appropriate for your CPU. If you are not certain, it is a safe bet to choose the <code>generic_64</code> or <code>generic_32</code> stage. Consult the [[Download]] page for more information.
+
 
+
Once the stage is downloaded, extract the contents with the following command, substituting in the actual name of your stage 3 tarball:
+
<console>
+
# ##i##tar xpf stage3-latest.tar.xz
+
</console>
+
  
{{important|It is very important to use <code>tar's</code> "<code>'''p'''</code>" option when extracting the Stage 3 tarball - it tells <code>tar</code> to ''preserve'' any permissions and ownership that exist within the archive. Without this option, your Funtoo Linux filesystem permissions will be incorrect.}}
+
example:
 +
searching for "amd phenom wiki" returns this [https://en.wikipedia.org/wiki/AMD_Phenom article] & the article says its "Microarchitecture K10"
 +
}}

Download/Browse Funtoo Linux Subarches

This page provides an overview of Funtoo Linux sub-architectures (also called subarches) designed for quick and easy reference. Funtoo Linux provides optimized installation images for all sub-architectures listed below. Clicking on a particular subarch will bring you to a detail page where you can learn more about that subarch and download a stage3 for installation.

How to Identify your CPU

There are a couple of ways to identify the type of CPU you have. One option is to use the lscpu command:

# lscpu


If the lscpu command is unavailable, you can get similar information via /proc:

# cat /proc/cpuinfo | grep "^model name" | uniq
model name	: Intel(R) Core(TM) i7-2640M CPU @ 2.80GHz


The cpuid command is another option and can provide other interesting information:

# emerge cpuid; cpuid | tail -n 1
Note

Search is your friend. Take the chip name gathered, then google wiki chipname to find the wikipedia article for your chip. The right hand column of your processors wiki article will list the microarchitecture.

example: searching for "amd phenom wiki" returns this article & the article says its "Microarchitecture K10"
